very good points.
my view is , if one sets up a recording rig, then one MUST be prepared to get into the tech to get the best from the rig. and take the bad with the good.
which is why , over the years , recording studios large and small often learnt electronics so they could do such things as fix an input channel on an audio mixing console (eg bad op amp) or a circuit card on a 2 inch 24 or 16 trak.
thus , if i get a prob in biab , i just resort to a workaround. but i stll love biab.
only game in town imho even tho i get frustrated sometimes.
this is an interesting thread on big sur i'm following, https://www.gearslutz.com/board/music-computers/1317296-macos-big-sur-version-11-share-your-experiences.html
very good points again. maybe one day we will get slimmed down pro audio OS's . perchance to dream.
what is interesting to note , is, OS problems might suggest somewhat why some studios buy custom computers made for recording studios.
like this that i lust after lol >> https://pcaudiolabs.com/rok-box-mc-x-series/
there are several vendors building custom studio pc's (see gearslutz.com)
ie you just turn the key. everything is optimised for recording work. includeing OS, recording software installation and sound device installation etc etc.
notice pcaudiolabs say they do lots of tweaks/optimise.
lots of big budget studios are getting big trak counts and plug in counts with the above types of custom systems.
